ContactMonkey supports both Outlook 365 and Outlook Non-365, with key differences in platform availability, tracking limits, and update methods. This comparison helps you understand which features are available for your version.
Platform Compatibility
The Web Add-in works on Windows, Mac, and Outlook Web (OWA). The Non-Web Add-in only works on Windows desktop.
Tracking Limits
The Web Add-in supports individual tracking for up to 1,000 recipients per email when added in the To field. The Non-Web Add-in supports individual tracking for up to 500 recipients per email when added in the To field.
Individual tracking means each recipient receives a personalized email that tracks their open and click behavior. If you need to send to more than 500 people, use the Web Add-in, switch to Overall tracking, or use a CSV file.
Scheduled Sending
Both versions support scheduled sending, but they work differently.
- The Web Add-in schedules emails through the cloud. Your email sends at the scheduled time even if Outlook is closed.
- The Non-Web Add-in requires Outlook to be running when the scheduled time arrives. If Outlook is closed, the email remains in your outbox and is sent when you next open Outlook.
For reliable scheduled sending without keeping Outlook open, use the Web Add-in.
Software Updates
- The Web Add-in updates automatically through the cloud. You always have the latest ContactMonkey features without manual action.
- The Non-Web Add-in requires manual updates 2-3 times per year. You need to download and install updates to access new features and bug fixes.
Shared Mailbox Support
Both Add-ins support sending from shared mailboxes. You need appropriate send-as permissions from your Exchange administrator.
Distribution List Sending
Both Add-ins let you send using distribution lists with the right permissions; however, accurate tracking is only guaranteed with the Web Add-in (more information here). Your IT administrator controls these permissions in your Exchange environment.
Add-in
Both versions include the ContactMonkey Add-in. This lets you insert emails, select tracking options, count recipients, and send or schedule campaigns directly from Outlook. They vary in functionality, which you can learn more about below:
